It was a hot afternoon when I fell in love with him that year. Rigao Ren felt sleepy and quietly became confused in math class. Suddenly, he felt a touch on his back. He turned around and the young man took off a piece of paper from his body. He then raised his head and looked at each other for ten seconds, his heartbeat pounding. Looking back again, my head was still dizzy, but my face was burning unconsciously. Three years have passed. It took three years to write a love letter and read it to you this summer. You are not too far away from the future, I just hope you will live up to your passing.
